How to Cut Multiple Parts From an MP3 Online (Free, No Upload)

You've got an MP3. Maybe it's a podcast with three ad breaks you want to remove. Maybe it's a lecture with dead air scattered throughout. Maybe it's a song with an intro and outro you don't need.

You search for a free online MP3 trimmer — and you find tools that let you drag two handles. One start point. One end point. One cut.

That's the problem. Most free audio trimmers only support a single selection. To make multiple cuts, you'd have to export, re-upload, trim again, repeat — or install Audacity.

There's a better way

MP3 Studio lets you mark as many cut regions as you want in a single session. Drag over any part of the waveform to mark it for removal, mark another section, then another — and export once with everything removed simultaneously.

Here's how it works:

1. Go to mp3-studio.vercel.app
2. Upload your MP3, WAV, FLAC, or M4A file (or drag and drop it)
3. Click and drag on the waveform to mark a section you want to remove — it turns red
4. Repeat for every section you want to cut
5. Click Preview to hear the result before committing
6. Click Export MP3 to save the final file

Why no upload?

Every step runs in your browser using WebAssembly. Your audio file never leaves your device. No server receives it. This matters especially if you're editing private recordings, confidential interviews, or personal voice memos.

What about precision?

MP3 Studio has a zoom slider that goes up to 2000×. That's not a typo. You can zoom deep enough to see individual milliseconds on the waveform and position your cut region to the exact frame. Most online tools max out at 128× zoom — which is fine for rough cuts but frustrating when you need to trim cleanly around a breath or a word.

Summary

If you need to remove multiple sections from an MP3 in one pass — free, without uploading your file to a server — MP3 Studio is the tool. No sign-up, no file size limit, no watermarks.
